}

Hi guys,
I was writing the String trim method in c and this is the code I came up with. I think it does the job of eliminating leading and trailing whitespaces however, I wish the code could be cleaner. Can you suggest improvements.
void trim(char *String)
{
int i=0;j=0;
char c,lastc;
while(String[i])
{

I have a non-Linux partition I want to encrypt with LUKS. The goal is to be able to store it by itself on a device without Linux and access it from the device when needed with an Ubuntu Live CD.
I know LUKS can't encrypt partitions in place, so I created another, unformatted partition of the EXACT…

Hi,
In older versions of Ubuntu, mainly 8.04, I could encrypt en entire partition using LUKS, and mount it as /. the /boot directory was mounted on another partition.

I'm moving over to Linux when the new SSD arrives. SSD gives increased performance, so I thought that I could encrypt everything.
But then I came to think about TRIM, and garbage collection on the drive. Will a LUKS encrypted drive affect the garbage collection system? (TRIM).
